MFJ Deluxe Versa Tuner II, MFJ-949E. The MFJ-949E is a 300 watt RF output power antenna tuner that will match any transmitter. The MFJ-949E uses a "T" matching network and covers all bands between 160 and 10.

THIS IS FOR RECEIVE ONLY. It will work with long or short random wire aerials or with aerials fed with coax cable. Unlike transmitting ATU's which must be low Q to avoid loss, the receive ATU should be high Q to enhance the signal as well as making the aerial resonant on the wanted frequency.

TheLDG Z100Plus has replaced the hugely popular LDG Z100. Full tunes take about 6 seconds. This simple device is still small, lightweight and is perfect for portable as well as sitting on your desk in your shack!

When matching to a low impedance antenna only a small amount of inductance is required to achieve the match. Conversely with an antenna a bit short for a quarterwave (or resonant at a higher frequency than required) more inductance and less capacitance is required.

The Z-817 is the ultimate autotuner for QRP radios including the Yaesu FT-817(D). The Z-817 interfaces to the CAT port (ACC) on the back of the FT-817 radio with the provided cable. Of course, the Z-817 will also function as a general purpose antenna tuner with other QRP radios.

Now this is rather special, it’s a beautifully constructed ATU. As you can see, the component selection and specification is top flight as is the build execution. Only thing spoiling my photos is I forgot to ewipe the dust from the front panel!

They are basically band-pass filters, simultaneously passing RF in both directions through the common connector while the band-pass filters provide a high degree of isolation between ports. High Pass: N Male.

The MFJ-901B is MFJs smallest and most affordable 200 Watt PEP Versa Tuner. Its designed to match virtually any transmitter (up to 200 Watts RF power output) to almost any antenna. It works continuously from 1.8 to 30 MHz.

This new model is ideal for the HF and VHF operator. It features high power handling up to 1000W. Accuracy is 5% on 5W, 7.5% on 20W, 10% on 200W and 12.5% on 400W. Weight 720g. 155 x 63 x 103mm. 13.8V DC Lamp.

The MFJ-959C Receiver Antenna Tuner/Pre-Amplifier is designed to properly match your antenna to your receiver for better performance from 1.8 to 30 MHz with a single antenna. Maximum signal power transfer occurs when the impedance of the antenna matches the impedance of the receiver.
